Mechano-biochemical marine stimulation of inversion, gastrulation, and endomesoderm specification in multicellular Eukaryota

Frontiers in Cell and Developmental Biology, 2022
The evolutionary emergence of the primitive gut in Metazoa is one of the decisive events that conditioned the major evolutionary transition, leading to the origin of animal development.

Employing BAC-reporter constructs in the sea anemone Nematostella vectensis [PDF]

Integrative and Comparative Biology, 2013
Changes in the expression and function of genes drive evolutionary change. Comparing how genes are regulated in different species is therefore becoming an important part of evo-devo studies. A key tool for investigating the regulation of genes is represented by bacterial artificial chromosomes (BAC)-reporter constructs. BACs are large insert libraries,

Role of MRTF in endo-mesoderm specification and gastrulation in Nematostella vectensis [PDF]

, 2022
reservedMRTF (Myocardin-Related Transcription Factor) is a unique transcriptional cofactor whose activity is regulated by cytosolic G-actin/F-actin ratio.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

Advanced Science, Volume 13, Issue 41, 22 July 2026.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

A muscle-specific transgenic reporter line of the sea anemone, Nematostella vectensis [PDF]

, 2010
The sea anemone, Nematostella vectensis, has become an attractive new model organism for comparative genomics and evolutionary developmental biology. Over the last few years, many genes have been isolated and their expression patterns studied to gain ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Evidences That Host Genetic Background More Than the Environment Shapes the Microbiota of the Snail Bulinus truncatus, an Intermediate Host of Schistosoma Species

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Microbiota have emerged as fundamental regulators of host physiology, shaping both ecological interactions and evolutionary trajectories. Yet, the determinants of microbiota diversity and structure in wild populations—particularly the respective roles of host genetics and environmental context—are still poorly understood.
